Question

我在texblocknumber.text =“123”中有一个值。当我每按一次按钮时，我想在堆栈中按下该值，然后在列表视图中显示堆栈值。我在上面的代码中有两个错误 1.我想在stack.Push（texblocknumber.text）中添加texblocknumber.text; 2.我想在列表视图中添加堆栈.push值

<ListBox Margin="0,0,-12,0" x:Name="mylist1">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <StackPanel>
                            <TextBlock x:Name="texblocknumber"  Text="{Binding datetime}" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                            <StackPanel Orientation="Horizontal" Margin="0,0,0,17">
                                <TextBlock x:Name="txt2"   Margin="5,0,0,0" Style="{StaticResource PhoneTextSubtleStyle}"/>

                            </StackPanel>
                        </StackPanel>
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>

c＃code

    static Stack<string> GetStack()
    {

        Stack<string> stack = new Stack<string>();

        stack.Push("fghj");
        stack.Push("bnmc");
        return stack;
    }

Answer 1

你可以使用按钮的绑定，并使用 Observable collection 作为列表的源代码而不是堆栈，因为它实现了 INotifycollectionchanged 。

Answer 2

just check this solution what i am doing in it on btn click i am saving content on a observablecollection..and simulataneously i have binded it to listbox..(i am showing with collection of string..you can do it with collection of objects too)..

你列表框..

<ListBox Margin="0,0,-12,0" ItemsSource="{Binding ListOFText}" x:Name="mylist1" VerticalAlignment="Top" >
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel>
                        <TextBlock x:Name="texblocknumber"  Text="{Binding }" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                        <StackPanel Orientation="Horizontal" Margin="0,0,0,17">
                            <TextBlock x:Name="txt2"   Margin="5,0,0,0" Style="{StaticResource PhoneTextSubtleStyle}"/>

                        </StackPanel>
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

你的page.cs ..

 public partial class MainPage : PhoneApplicationPage
{

    public ObservableCollection<string> ListOFText { get; set; }

    public MainPage()
    {
        InitializeComponent();
        ListOFText = new ObservableCollection<string>();
        this.DataContext = this;


    }

    private void Mubutton_Click_1(object sender, RoutedEventArgs e)
    {


        Button btnObj = sender as Button;
        ListOFText.Add(btnObj.Content.ToString());

    }


}
